Under gcc 4.7.2 20120921 (Red Hat 4.7.2-2) also cause this issue.
The root cause is:
for putback_lur_page() in mm/vmscan.c for next-20130621 tree.
the compiler assumes "lru == LRU_UNEVICTABLE" instead of report warnings (uninitializing lru)
The details are below, and the related info and warn are in
attachments, please check, thanks.
Next, I will compile gcc compiler with the gcc latest code, if also has
this issue, I should communicate with gcc mailing list for it.
Thanks.
